SHEAVE WHEEL.

Application filed February 13, 1922. Serial No. 536,071.

wheels, and particularly to that class of sheave wheel which is adapted to use with the endless cables of cable conveyors, and power transmission installations Where transmission blocks are clamped in spaced relation upon said cable.

It is the especial object of this invention to provide a wheel of the class described,

having improved removable cable supporting and driving members adapted to cooperate with the transmission blocks upon the cable, and which are adapted to convenient and expeditious adjustment to compensate for the elongation of the cable under the strains of protracted service.

The devices by which I attain this object are fully set forth in the following specification, and illustrated in the accompanying drawings of which- Fig. 1 is a side elevation of embodiment of my invention.

Fig. 2 is a sectional view line lI-II of Fig. 1.

Fig. 3 is a detail on an enlarged scale of one of the cable supporting and driving members illustrated in Fig. 1.

Like numerals reter to similar parts in the several figures.

In the drawing, the numeral l refers to a the preferred wheel in the rim 2. of which are formed pockets 3 adapted to receive the transmis' sion blocks 4 which are clamped in spaced relation. upon the endless cable 5 in the man ner common in cable conveyor practice. At their ends 6, the pockets 3 are contracted to receive the cable supporting and driving members 7, and the side walls 8 of these pockets are pierced. by transversely extending bolts 9 upon which said members are supported. Along the opposite lateral edges of the members 7 there are formed cable 10, adapted to support the cable 5, while both ends 11 of said members are taken along the shaped to engage the transmission blocks a and afford them a fair bearing.

The apertures 12 in the members 7, through which project the supporting bolts 9, are arranged in a line parallel with, but spaced from the longitudinal center line 13 of the driving members in such manner that by turning one side or the other outwardly, the efiective radius oi the sheave 1 may be varied by an amount equal to the eccentricity of the apertures 12.

In. practice, the wheels are commonly in allcd with the driving members 7 so turned as to produce a sheave of minimun'rradius,

and after the cable has become elongated by the strains of service, the bolts 9 may be removed, the members 7 turned other side out to increase the eii'ective radius of the sheave, and the bolts 9 replaced to hold them securely in position.

By the devices above described, I have produced a cable sheave of simple and durable construction which may be conveniently and expeditiously adjusted to accurately fit the spacing of the transmission blocks upon the cable to drive it. i

I claim:

1. In a cable sheave adapted to use with an endless cable having transmission blocks clamped in spaced relation thereon, the cornbination with a wheel, of pockets formed in the periphery of said wheel, bolts extending transversely through the side walls of said pockets, and cable engaging members supported upon said bolts and adapted to engage the transmission blocks on said cable, said. members having a plurality of cable supporting surfaces difl'erentially spaced from said supporting bolts, either o'l which may he turned outwardly to vary the efiective radius of the sheave and tor the purpose set forth.

2. Ina cable sheave adapted to use with an endless cable having transmission blocks differentially spaced from the supporting means in said pockets either of which may be turned outwardly to vary the ettective RBI hers having a plurality of cable supporting faces dilferentia-ll spaced from said supporting means, either of which may he turned outwardly to vary the effective 1'adius of the sheave as and for the purpose set forth.

In. testinion whereof, I a fiix my signature.
